Models, Views and Controllers

Had an interesting meetup about Android wear. All good, nice introduction to the new Complexity API, and general revision on optimization for power and other resources. It did get me thinking about MVC design patterns, and how I’d love the implementation to be. Model instantiate, model update, a model save callable, a view renderer, and a control list builder from method parameter signature. Very minimalist.

Initial thoughts indicate that the ordering of the controller events should be done based on the order of method occurrence in the class file for say Java. Also supplying a store state to the instantiate, and as a parameter to the store callback would be good. Like a Bundle. The renderer just needs a graphics context, and the controller callbacks need a unique method name (with some printed name mangling), and a boolean parameter to either do, or request doable for a grey out, and returning a boolean done, or doable status.

Synchronized on thread can keep mutual criticals from interfering, and a utility set of methods such as useIcon on the doable control query path could set up the right icon within a list with icons. This is the simplest MVC factorization I can envisage, and there are always more complex ones, although simpler ones would be hard. For post-process after loaded, or pre-process before saving, there would be no essential requirement to sub factor, although overrides of methods in a higher level object MVC may benefit from such.

Method name mangling should really be combined with internationalization, which makes for at least one existential method name printed form and language triad. This sort of thing should not be XML, it should be a database table. Even the alternate doable test path could be auto generated via extra fields in this table and some extra generation code, to keep the “code” within the “list field” of the editor. I’ve never seen a text editor backed by a database. Perhaps it could help in a “pivot table/form” way.

Just to say, I do like languages with a ‘ (quote) or “setq” or “Hold” method of supplying un-evaluated closures as function or method arguments. JavaScript has anonymous functions. Yep, okie dokie.

Technical. Well is mass information conservation the reason for dark energy via uncertain geometry and photon exchange? Is dark matter conservation of acceleration with a gradient field heavy graviton? Does the KODEK work yet?
